At the best of authors’ knowledge the only complete set of data from notched specimens is due to Huhn and Valtinat [5].
Two new fatigue sets of data are summarized in the present paper.
The reduction of the fatigue strength due to the presence of the zinc layer is fully investigated.
The SED approach was applied to a large bulk of experimental data: a final synthesis based on 900 fatigue data is shown in Fig. 5 [7], including results from structural steel welded joints of complex geometries.
Scatter band of 900 experimental data of welded joints made of structural steel is superimposed.

Front tension, especially back tension can cause rolling force certain degree reduction.
The wall thickness reductions of the former are nearly 5% more than that of the latter in the first and second stand, which results in an obvious increase on force parameters.
Transverse wall thickness precision In order to increase the reliability of data of distribution of transverse wall thickness, simulated workpiece should pass through the last stand a longer distance to keep up the stability of continuous-rolling status.
Data processing method was introduced in detail in Ref. [8].
Diameter increment reduction of rolled hollow tube is not obvious on the condition that front and back tension are small.

Analysis of absorption and reflection data indicates towards the reduction in optical band gap and increase in refractive index of the resulting nanocomposite.
In present work, Ag-PMMA nanocomposite films were prepared by chemical reduction method with thickness in the range of 20-30 µm.
Initially, the reduction of Ag+ ions leads to the formation of silver atoms (Ag0), which is followed by agglomeration into clusters [6].
UV-VIS absorption data was further analysed to calculate optical band gap and refractive index of Ag-PMMA nanocomposite films.

Analysis of surface roughness, burr on workpiece edges and cutter diameter reduction due tool wear was performed.
This research is one part of research on micro-milling of hardened materials regard to obtain of process prediction models, optimisation and micro-machininability data base development.
As the limit of tool diameter reduction can be take geometrical limit regard to process parameter or moment in time where is surface roughness sudden increasing over nominal values.
Fig. 7 Cutting tool diameter reduction (ap = 10 μm; fz = 8 μm; vc = 40m/min; MQL) Summary Analysing of machining process performance is very important in precision industry.
Base on experimentral data, modells and data base will be developed.

The Web can also overcome the incompatibilities of data formats through smart browsers and servers.
Moreover, there are some analysis and forecasting models here to aid project manager do some cost decision-makings using of data collected and processed by the WPCIMS.
Individuals comes from all participators of the project are teamed up as an information management team by the project manager to collect project cost data and to operate the WPCIMS.
The results indicate that the application performance of the WPCIMS is mainly including: 1)Processing efficiency promotion of project cost data; 2)Coordination improvement among participators; 3)Standardization and routinization of the project cost controlling workflows; 4)Dynamic and reasonable project cost decision-making; 5) Reduction of contract disputes; 6)Team knowledge increasing.
Meanwhile, data collecting and processing efficiencies has reduced by the extra organizational rampart come from the join-in of a new information managing department.

A real machine is finally manufactured and related data is measured and obtained according to the 3D model of the mechanical structure designed according to the plan and through the motion simulation on the 3D model.
The two speed-reduction stepping motors for clamping and shearing are fixed on the baseboard with screws.
We know from the data in Table 1 that the maximum total mass of spare parts is 17.899Kg.
The output torque of the shearing speed-reduction stepping motor is 6 N*M.

For CMB, both ambient data and specific source profiles are needed.
Because PMF is based on ambient data only, it is convenient to carry out VOC source identification and apportionment.
In order to avoid any unrealistic data distorting the source analysis result, some species that are not well-characterized.
The final data set contained 21 VOC species at MBT.
The vehicle related source contribution at MBT is generally similar to the data collected at Beijing (64%) and urban Milan (60-80%) and lower than that detected at traffic intersections (82~87% ).

It provides the basic life cycle impact data on REEs for ascertaining the environmental impact of intermediate and final products that use them [3].
The last part models the subsequent reduction of individual REOs to produce REEs.
Nominal representative data is used in this study.
The data have been sourced from review of technological processes [5-8], environmental data pertaining to materials and chemicals from LCA databases in SimaPro [9], and combined with modelling and estimation.
The environmental impacts from reduction of only those RE elements used in Mg-RE alloys are considered in this study.

By using Rist operating line for the indirect reduction zone, as seen in Fig.2, direct reduction degree of the new process can be calculated, and thus indirect reduction degree can be obtained.
Direct reduction degree equals y-coordinate of point B. 3.
Theoretical analysis of model results 5.1 Data used in the model In this study, data used in the model are derived from a real operating blast furnace in China.
Set VRG-h as 250 m3/thm, and keep other data unchanged.
